FDRAPPL is a high-performance, automated and flexible application
backup system, which is designed to backup a pre-defined group of
data sets that belong to a single z/OS application, regardless of
where those data sets reside.
The selected data sets are located through the MVS catalog,
so the user does not need to know the location of each
individual data set. A minimal number of SELECT statements are
usually required to identify an entire application. See the
technical detail section for examples
of FDRAPPL selection criteria.
FDRAPPL provides a fast and effective means of securing an MVS
application, and is ideal for complementing your existing volume-based
backup system (see FDRINC), or to provide additional, specialized
backup and retention for individual applications.
- Reduce application downtime and improve availability by
backing up only the required data sets.
- Write your FDRAPPL backups to disk (e.g. for home site
checkpoint restart/recovery) or to tape (for use in a disaster
- All major data set types supported, including CICS, DB2 and VSAM.
- Run your FDRAPPL backups before and/or after the application
has run, or even include them within the application workflow.
- Variable retention and expiration allows you to keep your
application backups for shorter (or longer) than your regular
- Protect your FDRAPPL backups against unauthorized access
by encrypting the backup data with FDRCRYPT.
- Flexible application restore facilities let you
recover the whole application, or individual data sets.
- Prioritize the recovery of your applications in
an emergency by restoring critical applications ahead of
less critical ones.
The table below (extracted from an March 2011 Performance Test)
demonstrates FDRAPPL's superior performance when compared to DFSMShsm
ABARS. As you can see FDRAPPL offers a clear advantage in performance
(i.e. reduced backup elapsed times) and resource utilization (i.e. less
CPU consumption and disk/tape EXCPs):
|ABR V5.4/75 with
FDRAPPL is a “managed” backup system, which means that
the details of all data sets that are backed up are recorded in a
special, high-performance control file, which requires minimum
DASD space – often only a few tracks. When a backup has
completed, a copy of its control file can optionally be
placed at the end of the backup type, to ensure that it is
available in a Disaster Recovery situation.
Recovery of your application with FDRAPPL couldn't be simpler. Because the
backups are fully “managed” (see above), restores are very
- No need to tell FDRAPPL which tape(s) or disk(s) were used to
store the backup – it already knows.
- Either the whole application or individual data sets
can be restored, either from the most recent backup, or
from an older one.
- Datasets can optionally be renamed during the restore
process, allowing you to create a copy of an application if
When we talk to Storage Administrators about their existing application backup
systems, the same problems and concerns are mentioned time and time again:
If your current backup system is suffering from any of the above issues, FDRAPPL
can provide you with a cost-effective solution. It is particularly suited to replacing
backup utilities such as IEBGENER or IDCAMS REPRO. It can also be used to replace your
DFSMShsm ABARS aggregate backups, or your DFSMSdss/DFDSS (ADRDSSU) dataset/application
- Poor performance and backup overruns are always of primary
concern, as slow backup performance invariably causes disruption to
the revenue-generating applications that are being backed up.
- High resource utilization and long-running housekeeping tasks
can consume valuable CPU cycles.
- A lack of control is often also cited as an issue, especially when
employing manual, un-managed backup processes.
